Merge pull request 'perf(meta-push): use cached api.config instead of deprecated loadConfig() — kills ~25% chronic baseline CPU' (#11) from fix/meta-push-use-cached-api-config into main

`pushMetaToMonitor` and `resolveAgentId` were both calling
`api.runtime?.config?.loadConfig?.()` to read the agent list. That
deprecated path (openclaw warns at gateway start:
"plugin runtime config.loadConfig() is deprecated; use config.current()")
synchronously rebuilds the full plugin-metadata snapshot — realpathSync
walks every plugin's package.json + manifest + source up the directory
tree, hashWatchedFiles fingerprints every watched plugin file, and
discoverInDirectory re-scans every `dist/extensions/<plugin>` (~100 of
them on prod t2). Each rebuild costs ~6-7s of gateway CPU.

`pushMetaToMonitor` fires every `reportIntervalSec` (default 30s)
from `hooks/gateway-start.js`. With 100 plugins that put the gateway
into a chronic ~22-30% CPU baseline even with zero agent activity. V8
profile 2026-05-27 08:14:00 60s window (0 turns, 2 metadata pushes
during): lstat 44.2%, statSync(buildInstalledManifestRegistryIndexKey)
6.9%, hashWatchedFiles via memo key 1.7%, all routed through
`readPersistedInstalledPluginIndexInstallRecordsSync` -> per-plugin
`discoverInDirectory`.

Switching to `(api as any).config ?? api.runtime?.config?.loadConfig?.()`
reads from the snapshot cache the gateway already maintains — the same
pattern already used elsewhere in this file (e.g. the calendar wakeAgent
dispatcher at line 284). Same change applied to `resolveAgentId` (only
runs once at start, but same anti-pattern).

This is a plugin-side perf workaround. The underlying openclaw bug is
that `loadConfig()` rebuilds the snapshot rather than returning the
cached one — a chronic 'all sync cache validity checks pay the full
discovery cost' design issue worth pushing upstream separately (the
walks per-call cost we measured here is unrelated to and amplifies any
agent-turn-triggered walk path).

 # HarborForge OpenClaw Plugin
 
-OpenClaw 插件：向 HarborForge Monitor 暴露 OpenClaw 侧元数据，并提供可选的本地桥接能力；安装时也可顺带安装 `hf` CLI。
+OpenClaw plugin that exposes OpenClaw-side metadata to the HarborForge Monitor, provides an optional local Monitor bridge, drives the HarborForge Calendar scheduler, and can optionally install the `hf` CLI.
 
-## 当前状态
+Part of the [HarborForge](../README.md) platform.
 
-- 插件注册名：`harbor-forge`
-- 旧 sidecar `server/` 架构已移除
-- 监控桥接走本地 `monitor_port`
-- 安装脚本支持 `--install-cli`
-- `skills/hf/` 仅在 `--install-cli` 时一并安装
+- Role: OpenClaw integration layer for HarborForge (registered plugin id: `harbor-forge`).
+- Talks to the HarborForge backend (`backendUrl`, default `https://monitor.hangman-lab.top`) for Calendar APIs.
+- Talks to a local HarborForge.Monitor bridge over `127.0.0.1:<monitor_port>` (no fixed default; commonly `9100`).
 
-## 项目结构
+## Current State
+
+- Plugin registration id: `harbor-forge` (was `harborforge-monitor`)
+- Plugin version: `0.2.0` (package manifests); telemetry reports `pluginVersion` `0.3.1`
+- Legacy sidecar `server/` architecture removed — telemetry is served directly by the plugin
+- Monitor bridge runs over the local `monitor_port`
+- Calendar scheduler integration (PLG-CAL-001 / 002 / 004)
+- Installer supports `--install-cli` and an optional managed Monitor (`--install-monitor`)
+- `skills/hf/` is installed only with `--install-cli`

-当插件配置了 `monitor_port`，并且 HarborForge.Monitor 也使用相同的 `MONITOR_PORT` 时：
+When the plugin has `monitor_port` configured and HarborForge.Monitor uses the same `MONITOR_PORT`:
 
-- Monitor 在 `127.0.0.1:<MONITOR_PORT>` 提供本地桥接服务
-- 插件可探测 `GET /health`
-- 插件工具 `harborforge_monitor_telemetry` 可读取 `GET /telemetry`
-- 如果桥接端口未配置或不可达，插件仍可正常运行
+- Monitor serves a local bridge on `127.0.0.1:<MONITOR_PORT>`
+- The plugin probes `GET /health`
+- The plugin tool `harborforge_monitor_telemetry` reads `GET /telemetry`
+- The plugin pushes OpenClaw metadata (version, plugin version, agents) via `POST /openclaw` on the `reportIntervalSec` cadence, enriching Monitor heartbeats
+- If the bridge port is unconfigured or unreachable, the plugin still works normally
 
-也就是说，这条链路是**可选增强**，不是插件启动或 Monitor 心跳的前置条件。

+If `managedMonitor` points to an installed HarborForge.Monitor binary, the `gateway_start` hook spawns it (passing `--backend-url`, `--identifier`, `--api-key`, `--monitor-port`, `--report-interval`, `--log-level` from the plugin config) and `gateway_stop` terminates it. Use `install.mjs --install-monitor yes` to build and wire this automatically.

+## Calendar Scheduler
 
-## 开发
+When `calendarEnabled` is true, on gateway start the plugin starts a Calendar scheduler that heartbeats the backend (`/calendar/agent/heartbeat`, `/calendar/agent/status`, `/calendar/agent/notify`) to receive and run scheduled TimeSlots, waking/spawning agents via the OpenClaw `spawn` API (with a notification fallback). Scheduler state is persisted to a state file; gateway restarts can be requested by the backend (PLG-CAL-004).

+# CalendarScheduler Refactor Plan (v2)
+
+> Updated 2026-04-19 based on architecture discussion with hang
+
+## Current Issues
+
+1. `process.env.AGENT_ID` doesn't exist in plugins subprocess — always 'unknown'
+2. Heartbeat is per-agent but should be per-claw-instance (global)
+3. Scheduler only handles one agent — should manage all agents on this instance
+4. wakeAgent used api.spawn (non-existent) → now uses dispatchInboundMessage (verified)
+
+## Target Design
+
+### Plugin State
+
+```typescript
+// Local schedule cache: { agentId → [slots] }
+const schedules: Map<string, CalendarSlotResponse[]> = new Map();
+```
+
+### Sync Flow (every 5 min)
+
+```
+1. GET /calendar/sync?claw_identifier=xxx
+   - First call: server returns full { agentId → [slots] }
+   - Subsequent: server returns diff since last sync
+2. Update local schedules map
+3. Scan schedules for due slots:
+   for each agentId in schedules:
+     if has slot where scheduled_at <= now && status == not_started:
+       getAgentStatus(agentId, clawIdentifier) → busy?
+       if not busy → wakeAgent(agentId)
+```
+
+### Heartbeat (every 60s)
+
+Simplified to liveness ping only:
+```
+POST /monitor/server/heartbeat
+  claw_identifier: xxx
+  → server returns empty/ack
+```
+
+No slot data in heartbeat response.
+
+### Wake Flow
+
+```
+dispatchInboundMessage:
+  SessionKey: agent:{agentId}:hf-wakeup
+  Body: "You have due slots. Follow the hf-wakeup workflow of skill hf-hangman-lab to proceed. Only reply WAKEUP_OK in this session."
+
+Agent reads workflow → calls hf tools → sets own status to busy
+```
+
+### Agent ID Resolution
+
+- **Sync**: agentId comes from server response (dict keys)
+- **Wake**: agentId from local schedules dict key
+- **Tool calls by agent**: agentId from tool ctx (same as padded-cell)
+
+## Backend API Changes Needed
+
+### New: GET /calendar/sync
+
+```
+GET /calendar/sync?claw_identifier=xxx
+Headers: X-Claw-Identifier
+
+Response (first call):
+{
+  "full": true,
+  "schedules": {
+    "developer": [slot1, slot2, ...],
+    "operator": [slot3, ...]
+  },
+  "syncToken": "abc123"
+}
+
+Response (subsequent, with ?since=abc123):
+{
+  "full": false,
+  "diff": [
+    { "op": "add", "agent": "developer", "slot": {...} },
+    { "op": "update", "agent": "developer", "slotId": 5, "patch": {...} },
+    { "op": "remove", "agent": "operator", "slotId": 3 }
+  ],
+  "syncToken": "def456"
+}
+```
+
+### Existing: POST /calendar/agent/status
+
+Keep as-is but ensure it accepts agentId + clawIdentifier as params:
+```
+POST /calendar/agent/status
+  { agent_id, claw_identifier, status }
+```
+
+## Implementation Order
+
+1. Backend: Add /calendar/sync endpoint
+2. Plugin: Replace CalendarBridgeClient single-agent design with multi-agent
+3. Plugin: Replace CalendarScheduler with new sync+check loop
+4. Plugin: wakeAgent uses dispatchInboundMessage (done)
+5. Plugin: Tool handlers get agentId from ctx (like padded-cell)
+
+## Files to Change
+
+### Backend (HarborForge.Backend)
+- New route: `/calendar/sync`
+- New service: schedule diff tracking per claw_identifier
+
+### Plugin
+- `plugin/calendar/calendar-bridge.ts` — remove agentId binding, add sync()
+- `plugin/calendar/scheduler.ts` — rewrite to multi-agent sync+check
+- `plugin/calendar/schedule-cache.ts` — already exists, adapt to multi-agent
+- `plugin/index.ts` — update wakeAgent, getAgentStatus to accept agentId

+ * Background
+ * ----------

+ * In multi-agent mode the plugin doesn't own a single cursor — one plugin

+ * This handle restores the same surface area (`isRunning / getCurrentSlot /

+ * the agentId/sessionKey supplied by the OpenClaw tool-factory context. The
+ * scheduler records the slot it just dispatched to each agent in
